“…Similar problems have been found with other registries. In a study of the Massachusetts Cancer Registry, 12% to 19% of new cases of melanoma were not recorded [20]. In an analysis of five regional cancer registries in England it was found that only 74% of cases of invasive melanoma were registered [21].…”

The calculation of incidence rates of melanoma in New Zealand has been hampered in the past by incomplete registration of cases. The aim of this study was to document the incidence of melanoma in the Auckland Caucasian population and to define the pathologic characteristics of these lesions. Data were collected for the Auckland region from the New Zealand Cancer Registry and the Auckland Melanoma Unit database for 1995 and combined with census statistics to give the crude and age-standardized rates for invasive melanoma. The results were analyzed by gender, morphology, body site, and thickness. The crude annual incidence for invasive cutaneous malignant melanoma was 77.7/100,000. The age-standardized annual rate was 56.2/100,000 with no statistically significant differences in the rates for males and females. The cumulative risk of developing melanoma over a lifetime, from age 0 to 74, was 5.7% overall. The age-specific rates steadily increase with advancing age. The lesions were generally thin; 64% were less than 0.76 mm, and only 7% were thicker than 3.00 mm. In conclusion, the Caucasian population in the Auckland region has the highest incidence of melanoma in the world.

“…However, in recent years, primary treatment has become less extensive, and many patients are treated in doctor's offices, and thus were missed by SEER. 18,19 The age-contours reported here, as well, will have smaller increases or larger decreases over time than they should have. However, this loss of data that was selective over time would have needed to be larger in the youngest groups, and there is no evidence of this.…”

The rise in the incidence and mortality from melanoma of the skin is slowing down in younger age groups in the United States. In many White populations, including that of the US, melanoma incidence and mortality rates increase according to proximity of residence to the Equator. Variations with age in this gradient do not seem to have been examined. We examined how the influence of latitude on melanoma rates varied with age. Estimates of age-specific trends by time and by latitude for natural logarithm (Ln) melanoma incidence-rates from the Surveillance, Epidemiology and End Results (SEER) programs, and Ln melanoma mortality rates from the US Vital Statistics were derived from fitted regression equations. Unexpectedly, a decline from old age to youth in the influence of latitude was found for both incidence and mortality from melanoma of the skin in males, and for mortality in females. Further, these changes in the relationship to latitude with age correlated with the changes in time trends with age. The link with exposure suggests that the time trends in melanoma are driven by variations in damage to melanocytes in early life that increases sensitivity to sunlight. This has implications for the general understanding of melanoma etiology and for health education.

“…They reported that 25% of all cases of melanoma were reported from independent laboratories, which may contribute to the discrepancy. 21 Koh et al 22 estimated that between 12% and 19% of new cases of melanoma were not reported to the Massachusetts Cancer Registry. These estimates of large discrepancies occur because of the wide variety of nonhospital settings in which melanoma is diagnosed and treated.…”

Objective: To identify the change in the incidence of cutaneous melanoma over time among young adults. Patients and Methods: Using Rochester Epidemiology Project data, we identified patients aged 18 to 39 years who had a first lifetime diagnosis of melanoma from January 1, 1970, through December 31, 2009, in Olmsted County, Minnesota. Demographic and clinical information, including survival, was abstracted, and estimates of the incidence of melanoma and overall and disease-specific survival were generated. Results: From 1970 to 2009, the incidence of melanoma increased by 8-fold among young women and 4-fold among young men. Overall and disease-specific survival seemed to improve over time; hazard ratios comparing year of diagnosis with mortality were 0.92 and 0.91, respectively. Conclusion: The incidence of cutaneous melanoma among young adults is rapidly increasing, especially among women. Continued close monitoring of this high-risk population is necessary.
